Did you

Did you really think that trying
to remove my memory from
your mind would really work?
When you became a part of my
life I became a permanent
part of your body. I am inside
of every limb, and you can
try to scrub yourself clean
of me but I can promise you
that no amount of soap and water
will ever free you from the effect
that I had on your entire being.
